UNITED STATES GEORGE S. HENLEY, OF ROCHESTER, NEW YORK.

Specification of Letters Patent.

Patented Oct. 5, 1920.

Application led January 30,'11920. Serial No. 355,050.

To all whom t may concern: A

Be it known that I, Grenen S. HENLEY, residing at Rochester in the county of Monroe and State of ew York, have invented new and useful Improvements in Locks, of which the following is a specification.

This invention relates to locks for doors, and is primarily designed for use in connection with a vestibule door, or a door of a receptacle wherein bottles containing milk are adapted to be placed by the party delivering the same.

The invention essentially enibodies a locking bolt yieldably mounted upon the door amb, and adapted to automatically engage a keeper carried by the door, when the locker is closed.

The chief characteristic of the present invention resides in the provision of means whereby the locking bolt can be normally maintained in an inactive or unlocked position, to permit access to be had to the vestibule or receptacle wherein the bottles of milk are to be placed, the means for this purpose being manually operable so that the party delivering the milk can subsequently release the bolt so that the latter will automatically enga e its keeper when the door is closed, and t e door locked from the inside.

The nature and advantages of the invention will be better understood when the following detail description is taken in connection with the accompanying drawings, the invention residing in the construction, combination, and arrangement of parts as claimed. g

In the drawings forming part of this specification, like numerals of reference indicate similar parts in the several views and wherein:

Figure 1 is a vertical section taken through the door, showing the manner of locking the same, the lock casing being disposed in elevation.

Fig. 2 is a sectional view taken through the lock casing and at right angles to Fig. 1.

Fig. 3 is a horizontal section through the door and the mechanism in plan.

Fig. 4 is an enlarged transverse sectional view through the lock casing.

Fig. 5 is an enlarged vertical sectional View therethrough.

The lock casing in which the locking elements are arrangedfor sliding movement, may be constructed from any suitable material, and embodies a rear wall 10 substantially of rectangular formation, and a front wall 11 of substantially U-shaped formation 1n cross section. The parallel sides 12 of the front wall terminate to provide laterally disposed anges 13 which lie against the back Wall 10. The flanges 18 are cut away at their edge as at 14 to receive the inbent tongues 15 carried by the opposite longitudi nal edges of the back wall 10, and the front wall 11 is then slid upon the hack wall to arrange the eut away portion 14 below the tongues 15, so that the latter will serve to hold the front and rear walls operatively associated. The back wall 10 is provided with openings 16 similar to the openings 17 formed in the flanges 13 of the front wall, and these openings are adapted to register with each other when the front wall is finally positioned upon the back wall for the reception of suitable fastening elements .18 which secures the casing to the door caslng A. The upper edge of the back plate 10 is ent around the adjacent edge of the front wall 11 as at 19 and terminates to provide the lugs 20, which latter are formed to provide bearings 21 for a purpose to be hereinafter described. It will be noted however that the lugs 20 assist the ears 15 in holding the front wall positioned upon the rear wall 10.

Arranged to reci )recate within the casing defined by the ront and rear walls 10 and 11 respectively, is a bolt including a relatively large head 22 and a reduced stem or body portion 23, the latter sliding through an opening in a fixed transversely disposed plate 24 arranged within the casing. A coiled spring 25 encircles the stem 23 of the bolt and has one end bearing against the head 22 thereof, while the opposite end of this spring bears against the fixed plate 24, whereby the spring functions to normall maintain the head of the bolt projected eyond the upper end of the casing. VThe lower end of the holt is provided with a nut 26 arranged beneath the plate 24. An arm 27 connects the bolt with a. crank rock shaft 29 in the bearings 21, and this arm has an offset extremity 30 which is bifurcated and straddles the bolt between the nut 26 and the fixed plate 24. The opposite extremity of the arm 27 terminates at a right angle 31 which engages the crank portion 32 of the rock shaft 29. This allows the lock to be readily reversed for a right or left handed door. One end of the rock shaft 29 is formed to provide an enlarged ring 33 Which may be grasped to conveniently operate the belt to return the latter against the tension oiE the spring 25 when the occasion requires. The opposite end of the rock shaft 29 is bent as at 3l to cooperate with a leai' spring 35 for holdin r the bolt retracted against the tension oi: the spring 35. The leaf spring 35 has oneend secured to the door B and its opposite end slightly spaced therefrom and disposed in the path of movement of the offset extremity 34 of the operating element. Manifestly When the operating element 29 is rotated in the proper directlon to retract the bolt 23, the bent extremity 3i ol said operating element passes over the spring 35 and when moved out of engagement therewith, the spring assumes a position in cn gagen'ient with the bent extremity 34 to hold the bolt retracted. As above stated, the lock casing is secured upon the door casing A, while a keeper 36 projects from the door and is adapted to be automatically engaged by the head of the bolt when the door is moved to closed position.

In practice, the handle 33 of shaft 29 is moved to horizontal position, at which time the operating element 29 is rotated in a di rection to retract the bolt against the tension of the spring 25. In this position of the ring 33, the bent extremity 34 of the operating element is engaged by the spring 35) to hold the bolt retracted. 1f desired, any empty milk bottle may be arranged upon the ring to assist the spring 35 in holding the bolt in its inactive position, it bein of course understood that the empty milk bottle being left in the vestibule will be collected by the milkman.

With the bolt 23 thus held in inactive or retracted position, the door B is free to be opened by the party delivering the milk and permitting access to be had to the vestibule of the building. After the milk to be delivered has been positioned Within the vestibule, the milkman rotates the operating element 29 by moving the ring 33 to a veru tical position to release the bent extremity 34 from the spring 35, thus ermitting the spring 35 to project the bolt rom the upper end of the casing. Manifestly with the boltl in this position7 it is only necessary to move the door to its closed position whereupon the bolt will automatically engage its keeper 36 to lock the door.

The mechanism forming the subject matter of the invention, is also applicable to that class ot' devices or receptacles, associated with the doors or Windows for receiving milk bottles, wherein the door or Window forms the back Wall of the receptacle. As is obvious the door is locked from the inside and necessitates the manual operation of the element 29 to effect its release.

While l have shown and described what l consider the preferred embodiment of the invention l desire to have it understood that i do not limit myself to the precise construetion and arrangement of parts disclosed, inasmuch as such changes may he resorted lo when desired as fall within the scope oi what is claimed.

llaving thus described my inveinion what l claim is:

1. A lock comprising a keeper, a sliding bolt, yieldable means for holding said bolt engaged with its keeper, a rotatable element having a crank portion connected With the adjacent end of said bolt whereby the latter is retracted When the said element is rotated, a right angularly disposed portion forming one end of said element, and a resilient member being disposed in the path of' movement of said right angularly disposed portion to engage the latter for holding said bolt retracted.

2. A. lock comprising a casing, a keeper, a bolt slidably mounted Within the casing, yieldable means for holding said bolt engaged with its keeper, an element journaled within the casing and projecting beyond the opposite sides thereof, a connection between said element and bolt whereby the latter is retracted upon movement of the element in one direction, one end of said element terminating to provide angularly disposed manipulating portions, the opposite end of the element being off-set, and al resilient member disposed 1n the path of movement of said offset portion to engage the latter for holding the bolt retracted.

ln testimony whereof l affix my signature.

GEORGE S. HENLEY.
